Count Us In, Ep 8: How many are left?

SUBJECTS:  Maths

YEARS:  F–2


Flynn and Dodly are practising their magic tricks.

They are trying to make eggs, muffins and even guinea pigs disappear.

Help our two friendly monsters work out how many should be left after their disappearing tricks.


Things to think about

  1. 1.Practise counting forwards and backwards. If five little monkeys were jumping on the bed and one fell off and bumped his head, how many monkeys would be on the bed then? Continue until there are no more monkeys jumping on the bed.
  2. 2.While watching this video, try counting backwards as the eggs disappear one at a time, the peas are eaten, the muffins are removed, the eggs hatched and the birds fly away, to see how many are left each time.
  3. 3.Model some subtraction magic tricks of your own. Use counters or toys then do your magic and make some disappear. How many do you have left? Draw your magic trick and write the numbers next to your pictures.
  4. 4.Set up a ten-pin bowling lane using plastic bottles and a tennis ball. As you bowl over the pins, work out how many of the ten bottles were knocked over and how many were left standing. Write down how many were left standing and how many were knocked over after each game.
